Blockchain applications for records that several organisations share

A business needs a blockchain when several independent organisations must write to and rely on the same record, and no single party is trusted to control it. If one organisation owns the data and others only read it, a conventional database with access controls and signed audit logs is usually cheaper, faster and easier to change. We test each project against these conditions during discovery and put the recommendation in writing.

A public blockchain lets anyone read the ledger and submit transactions, while a permissioned blockchain limits participation to approved organisations. Public networks give the strongest independent verifiability and suit records that outsiders must check, such as certificates. Permissioned ledgers offer more privacy, predictable costs and control over who validates entries, which suits a consortium of known partners. Some designs combine both, keeping detail on a permissioned ledger and anchoring periodic proofs to a public network.

Personal data should generally not be written directly to a blockchain, because ledger entries cannot be erased and data protection law gives people rights to correction and deletion. Our designs keep personal data off-chain in a database you control and place only pseudonymous identifiers, hashes or proofs on the ledger, so deleting the off-chain record breaks the link. We build with UK GDPR in mind and work within the legal and compliance advice you receive for each design.

A blockchain connects to existing systems through an integration layer of APIs, event listeners and indexers that we build alongside the ledger. When your ERP records a shipment, the integration signs and submits the matching ledger event, and the confirmed result flows back. Indexed copies in PostgreSQL let reports and dashboards query ledger data quickly, while scheduled reconciliation jobs flag any mismatch between the chain and your systems.

Costs depend on scope; we give a fixed quote after discovery. The main drivers are the number of participating organisations, the network type, how much on-chain logic is needed, the systems to integrate and whether an independent security audit is required. We also estimate running costs, including transaction fees, node hosting and indexing infrastructure, so you can judge the total cost of ownership before committing to production.

The length of a blockchain proof of concept depends mainly on how many participants and systems are involved and how quickly partners can supply real data. Limiting it to one event type and a small group of participants keeps it short, and you review working software every one to two weeks. Production rollouts with partner onboarding, security audits and governance agreements take longer, so we plan them in phases once the proof of concept has shown the design works.

Control of a shared ledger is set by a governance model that participants agree before launch. It defines who can join or leave, who runs validating nodes, who may approve changes to shared logic and how disputes are handled. We help shape the technical side of these rules and enforce them through permissions, multi-signature approvals and upgrade procedures, so no single participant can quietly rewrite the shared record.

We match key custody to the value and risk each key carries. Organisational keys are held in managed key services or hardware-backed signers rather than in code or configuration files, with separate keys for separate roles, rotation schedules and documented recovery steps. High-impact actions such as upgrading on-chain logic or moving held assets need approval from several keyholders, and every signing request is logged for later audit.

Confirmed blockchain data is extremely difficult to alter, but that does not make it accurate. A ledger proves that an entry has not changed since it was written and shows who signed it; it cannot prove the original information was correct. That is why our designs focus on who is allowed to write each record, how inputs are validated before submission and how corrections are added as new, linked entries rather than edits.

Yes, where the asset, legal structure and regulatory position support it. Tokenisation represents ownership units, credits or entitlements as tokens on a ledger, so balances and transfers are recorded in one shared place. We design the token model, registry, transfer restrictions and links to your onboarding and reporting systems. Whether a token counts as a regulated instrument in your market is a question for your own advisers, and we design within their guidance.

Yes, provided the network is chosen carefully and the ledger's job is kept narrow. We avoid writing every system event on-chain; instead we batch records, anchor periodic proofs, or use permissioned ledgers and layer 2 networks where volumes are high. Indexed off-chain databases handle search and reporting, so screens respond quickly regardless of block times. We load test the integration layer before launch to confirm it copes with peak activity.

After launch we can take on node and indexer monitoring, key rotation, dependency updates, partner onboarding and planned upgrades, each carried out through the agreed governance process. Source code, documentation and infrastructure definitions are handed over under the terms of your project contract, so your own team can take the system over at any point. Ongoing support is most useful in the early months, while new partners join, data volumes grow and usage patterns settle.

Blockchain development covers the whole ledger-backed system, while smart contract development focuses on the on-chain programs that enforce rules inside it. A blockchain project includes the choice of network, governance between participants, node hosting, key custody and integration with ERPs and databases. Smart contract work concentrates on the logic itself: its permissions, tests and audits, and the wallets and interfaces people use to call it. Many projects need both, so we plan the boundary between them at the start.
